Based on the information given, the correct statement is Option 4: The graph is not provided, so we cannot determine if it is always increasing.
The question mentions a graph of the student's distance during the journey to school, but it does not provide any specific details or the actual graph itself. Without the graph or any additional information, we cannot accurately determine whether the distance is always increasing or not. The graph could have various shapes and patterns depending on factors such as the student's mode of transportation, stops along the way, or any detours taken.
